Operation

Materials of Construction

●Differential pressure is limited to maximum 150 psig (10.3bar)when reverse flow occurs.

● Throttling reverse flow may damage O-ring.

●D-pro plug valves provide positive shut-off, high flow capacity, and quick quarter-turn operation.

●D-pro plug valve provides flow throttling capability.

Safe Valve Selection The selection of a valve for any application or system design must be considered to ensure safe performance.Valve function, valve rating, material compatibility, proper installation, operation and maintenance remain the sole responsibility of the systemdesigner and the user. Dk Tech accepts no liability for any improper selection, installation, operation or maintenance.

We reserve the right to change the specifications stated in this catalog for our continuing program of improvement.

Factory Test● Every V23 series plug valve is factory tested for shutoff at 600psig (41.3 bar).

PTFE-coated FKM is standard. Choose optional O-ring material forfluid compatibility and system temperatures.

Optional vented plug and valve body provides system pressure releaseto atmosphere when valve is closed. ● This option reduces the maximum operation pressure to 150 psig (10.3 bar).● To order, use designator - VH. See how to order.
